You may think that a condom can be used again. After all, it looks tough, takes a lot of friction and thrusting, and withstands all the heat! But sadly, condoms cannot be used more than once. They are made to be one-offs.
They are the barriers to all the nasty STIs and STDs and so they shouldn’t be used again. Also, they cannot be washed and reused because there is no way to assure that the STIs/STDs are cleared off the used condom.
